FROM THIS EPISODE

The web was invented just 25 years ago by a British physicist with a strong sense of Western values. But it's China and India that are adding billions of new users. What can be done about censorship as the worldwide web becomes truly worldwide. Also, all eyes are on Sunday's referendum in Crimea, and reintroducing an overlooked civil rights leader.

Russian troops are deployed along the border of Eastern Ukraine, but President Vladimir Putin says he won't decide what to do until after the Crimean referendum on Sunday. In London today, after six hours of talks with Russia's Foreign Minister, Secretary of State John Kerry said the US has already staked out its position. "We believe the referendum is contrary to the constitution of Ukraine, is contrary to international law, is in violation of that law, and we believe it is illegitimate."

The web was invented 25 years ago by a British physicist with a strong sense of Western values. Sir Tim Berners-Lee still envisions a free, open, democratizing system of universal communication. Berners-Lee has recently advocated a digital Bill of Rights to protect against the growth of government censorship that Google's Eric Schmidt calls "mechanisms of repression." In China, citizen bloggers can be arrested. Pakistanis can't watch YouTube; and Russians won't read independent websites about Ukraine. Censorship and privacy violations reveal limits to the Global Village as the worldwide web becomes truly worldwide.

His is a name seldom remembered in the context of America's Civil Rights Movement, but he deserves a place alongside Malcolm X and Dr. Martin Luther King, Jr. That's according to a new biography — the first -- about Stokley Carmichael's life. Peniel Joseph is a history professor at Tufts University and the author of Stokely: A Life. The Trinidad-born, New York educated Carmichael spent his 20th birthday in jail in Mississippi, where he helped organize freedom rides. In 1966, he was head of the Student Non-Violent Coordinating Committee. Two years later, he left this country to live in Africa.
